Overview

Overview
Module Description
The Modbus TCP (MBTCP) Gateway Module provides a
control link between a Modbus TCP fieldbus and a sys-
tem that uses Graco Control Architecture (GCA). This
link provides the means for remote monitoring and con-
trol by an external automation system.
Data provided by the MBTCP Gateway Module to the
fieldbus depends on the GCA-based system. Mapping
of Modbus registers is loaded by the host GCA system
and varies by system.
Data Exchange
Data is available by block transfer or by explicit access
to individual attributes as defined by the fieldbus specifi-
cation.
